Updating dependencies

To check if dependencies in using directives are up-to-date, use dependency-update command:

//> using dep com.lihaoyi::os-lib:0.7.8
//> using dep com.lihaoyi::utest:0.7.10

object Hello extends App {
  println("Hello World")
}

scala-cli --power dependency-update Hello.scala

Updates
   * com.lihaoyi::os-lib:0.7.8 -> 0.8.1
   * com.lihaoyi::utest:0.7.10 -> 0.8.0
To update all dependencies run: 
    scala-cli dependency-update --all

Passing --all to the dependency-update sub-command updates all dependencies in your sources.

scala-cli --power dependency-update Hello.scala --all
